Pop star Peter Pan wannabe Michael Jackson, who stands accused of plying a young cancer patient with wine to get him to submit to his sexual advances, has been treated for alcohol and drug abuse on a number of occasions, according to a new bombshell report.

The bizarro former boy wonder has been in and out of rehab because of an addiction to Demerol and morphine, writer Maureen Orth charges in the upcoming issue of Vanity Fair magazine.

At least one of his stints in rehab reportedly came at the behest of his good friend Elizabeth Taylor. That was back in 1993, when the superstar was hit with his first round of child-molestation charges.

According to Orth, a doctor contacted one of Jackson’s advisers and warned him, “Either the drugs are going to kill him or he’s going to die by flying out of a window because he thinks he can fly. You better get someone here he’ll listen to.”

Taylor, a rehab veteran, intervened and got whacked-out Jacko to check himself into a London detox center, Orth says.

Several years later, Jackson was put through detox in Seoul, South Korea, by Dr. Neil Ratner, a former rock drummer turned anesthesiologist, according to Orth.

“We were getting Michael off what he was addicted to – Demerol and morphine,” former Jackson business adviser Myung-Ho Lee told Orth.

On another occasion in the 1990s, Lee said, he had to pick the superstar up off the floor of a plane and help him stagger off after they landed in Frankfurt, Germany.

Lee recalled that when he told Jackson’s security people, “You can’t get drunk like that on white wine,’ they replied, “it’s not only wine, but that he takes pills with it,” Orth reports.

He sometimes shares his juiced-up soda cans with young friends, Orth says.

The 13-year-old cancer patient at the center of current sex-abuse charges claims Jackson gave him wine in Coke cans last February on a Florida flight – while his mother sat nearby totally unaware that the plane wasn’t the only thing flying high.

Lee recalled an earlier occasion when the King of Pop blew a megabucks business deal because he provided wine-filled soda cans to a teenager.

He said Jackson’s plans to open a series of theme parks and toy stores in Japan were deep-sixed in 1998 after he took the 13-year-old son of one of his new Japanese partners to an amusement park and got him drunk on cans of “Jesus juice.”

Among the other revelations in Orth’s article:

* Jackson’s young accuser has provided police with drawings of the superstar’s private parts – as did the teen whose family dropped charges against the singer in 1993 after a megabucks payoff.

* The teen claims underwear he wore during his visits to Neverland went missing – which is consistent with a report that Jackson kept the underwear of his young overnight guests.
